Why APPI:  Moving a rolling load 20 feet with a hand winch may not seem to be an onerous task.  However, if your job was cranking one back and forth during a 12 hour shift you too would celebrate when two of our WD2500 AC electric winches arrived and replaced the painfully slow and laborious manual units.

Configured to work in a hazardous environment, the compact planetary reduction winches move a riffler which spreads iron oxide pellets evenly into the smelting furnace below it.  In this operation, one winch pulls while the line is pulled off the other winch under tension.  This arrangement keeps the lines tight and eliminates the delays and costs associated with wire rope that does not spool properly.

Richard Murry, the mechanical engineer for the plant, confirmed the system is performing as designed.  He also indicated the operators never fail to express their gratitude for the new system.
